Definitions

  • This invention relates to apparatus for the automatic feeding or insertion of flat items such as cards, and, more particularly, to apparatus for inserting or feeding one flat item at a time.
  • rollers seize a card when it is inserted.
  • the photocells sense the card and inhibit the entry of another card until the seized card has been fed to a further conveyance or a step-by-step feeding device in the case of punched cards.
  • Other known arrangements depend on an operator to feed cards in singly and at a minimum rate.
  • the invention is characterized by the fact that the distance between the center of the feed roller of the quick insertion and the center of the evaluating device is shorter than the length of one punched card, and that over both there extends a rocker which, from a neutral initial position is unblocked by the insertion of a punched card and presses the latter against the feed roller.
  • the rocker retains this position until the previously transported card, by meeting against a stop limit, completes the circuit of a control magnet which, in turn, tilts the rockerinto a position in which the punched card is brought into engagement with the step-wise advanceable feed device.
  • the rocker is now held in this position until, by the end of the card, a sensing lever is released for interrupting the circuit of the said control magnet, thus permitting the rocker to return to its neutral initial position.
  • FIG. 1 shows an arrangement according to my inven tion in the ready-to-operate normal position, which is particularly adapted to operate with slotted or edgecoded cards provided with feed holes;
  • FIG. 2 shows the arrangement of FIG. 1 at the moment in which the inserted punched card has assumed the proper position in relation to the sensing or scanning device;
  • FIG. 3 shows the arrangement according to FIG. 1 in the condition where the punched cards are evaluated
  • FIG. 4 shows a plan view of the arrangement according to FIG. 1;
  • FIG. 5 shows the circuit arrangement of the control magnet of my inventive arrangement.
  • the arrangement according to the invention is adapted to the processing of slotted or edge-coded cards which are provided with feed holes.
  • the special construction which is required on account of this fact, however, does not prevent the arrangement, by maintaining its characteristic features, from being designed capable of processing also normal types of punched cards without feed holes or similar types of flat items.
  • the arrangement according to the invention is provided with a feed roller 4 which is continuously rotated in the direction indicated by the arrow.
  • the feed roller 4 may 'be provided with a rubber coating.
  • Roller 4 according to its function as a highspeed or quick insertion device, has a relatively high circumferential speed. Between it and the beaded sprocket wheel 19, which is part of the not shown stepping device, there is a distance which is shorter than the length of the cards to be inserted.
  • the two feed members 4 and 19 are so ararnged in the conventional way opposite a guiding table 8, that they project from below it through recesses, and in accordance with their function, above the upper surface of the table.
  • FIG. 4 the rear longitudinal edge of guiding table 8 is in alignment with a vertical guide sheet 30 which, simultaneously, may form part of the housing of the equipment. For reasons of clarity this part has been omitted in FIGS. 1-3.
  • Rocker 1 is arranged over the two feed members 4 and 19. This rocker is pivoted on a firmly arranged bolt 2.
  • the arrangement of the rocker 1 is that it, in the neutral initial position as shown in FIG. 1, is so positioned over the feed members 4 and 19, that between the circumference thereof and the bottom side of the rocker 1 there is a distance permitting the free insertion of a single punched card.
  • Rocker 1 is acted upon by a spring 3 which urges the rocker into a counter position against feed roller 4. According to FIG. 1, this is prevented by a locking lever 5 which is designed in accordance with FIG. 4, and which, under the action of the spring 7, always tends to assume the position as shown in FIG. 1, in which the lever 5 with its face edge 11, comes to lie underneath the blocking bolt 6 of the rocker 1.
  • FIGS. 1 and 4 Its other end, according to FIGS. 1 and 4, extends through the opening 9 of the supporting wall 8a extending rectangularly in relation to the supporting table 8, and projects upwards through the supporting table 8 to such an extent into slot 10 of rocker 1, that the inclined portion 29, in its lower half, constitutes an acute angle with the bottom side of the rocker.
  • Rocker 1 is connected to a switching rod 12 by means of pin 13.
  • One end of switching rod 12 is in a formlocking connection with the armature 24 of a control magnet 23.
  • Armature 24 controls contact 25 which is closed when the armature is in the attracted condition.
  • the switching rod 12 is provided with a rectangularly bent extension 12a which is provided with an adjusting or set screw 14.
  • the contact 17 is opened, because the switching spring 18 with its front beaded end, is held downwards by the actuating portion 26 of limit-stop lever 15.
  • Limit-stop lever 15 is pivotably mounted and is connected to spring 16 which establishes the normal position shown in FIG. 1.
  • the actual limit stop 28 of lever 15 is set-01f at the side according to FIG. 4. It projects through the guide sheet 30 into the plane of the rocker 1.
  • Both the length and the width of the limit stop 28 are chosen so that it, throughout the width of the rocker 1, projects to such an extent downwards over the latter, that in the position of the rocker 1 shown in FIG. 2, there is provided a reliable limit stop for an inserted punched card, but that a release of the punched card is effected whenever the card has assumed the position as shown in FIG. 3.
  • the swivel range of the lever 15 or its limit stop 28 respec- 3 tively, is determined by an adjustable limiting member 27.
  • a sensing lever 20 which, according to FIG. 1, is pulled with its lower arm against a limit stop 29 by the action of spring 22.
  • a contact 21 which is open in the aforementioned position of the sensing lever 20.
  • the upper arm of the lever 20 projects slantingly through an opening of the guide table 8 in the upward direction.
  • the rocker 1 according to FIG. 4 is provided with slot-like recesses 33 and 34.
  • the driving shaft of the feed roller 4 is slantingly arranged with respect to the vertical line by the amount of the angle 0:.
  • a card is always caused to meet against the guide sheet 30, irrespectively of whether the card is inserted straight or slantingly.
  • this arrangement does not require any special guiding devices.
  • this contact is arranged in series with the control magnet 23 and a voltage potential is maintained across the series connection so that the magnet will attract and, via the switching rod 12, pull rocker 1 into the other operating position, in which the punched card 32 is released from the drive by the feed roller 4, for being engaged to the beaded sprocket Wheel 19 of the evaluating station ahead.
  • This amount x equals the distance of the third feed hole 31 from the front edge of the card.
  • the respective adjustment is effected via the correspondingly adjustable limiting device 27.
  • the sprocket wheel 19 which is at a standstill at this particular time position, is so adjusted that one of its feed pins will point vertically upwards so that the latter (FIG. 3), upon attraction of control magnet 23 will engage the feed hole of the punched card 32 which is pressed down by rocker 1. Also, the sensing lever 20 is turned in opposition to the action of its spring 22, thus closing the contact 21 assigned thereto. At the same time there is effected a reopening of the contact 17 because the set screw 14 in the projecting portion 12a of the switching rod 12 causes a pressing-down of the switching spring 18 by the attracting motion of the magnet armature 24 which thus also actuates its contact 25.
  • the set screw 14 is adjusted in such a way that the contact 17 is only open after the contact 21 has closed. According to FIG. 5 it is safeguarded in this way that the control magnet 23 is continuously energized.
  • the contact 25 By the action of the contact 25 the (not shown) stepping mechanism of the sprocket wheel 19 is switched on and the likewise not shown evaluating device is released, with the latter effecting the sensing of the perforation of the punched card 32 which is advanced in a step-by-step manner by the sprocket wheel 19.
  • the contact 21 is opened on account of the fact that the lever 20 is moved by spring 22 back to its normal position, so that in accordance with FIG. 5 the magnet 23 is deenergized, and the armature 24 drops off. A further stepping-on is prevented due to the release of contact 25.
  • the above described arrangement may also be designed for the use with punched cards without feed holes.
  • the sprocket-wheel feed merely has to be replaced by a friction-roller feed.
  • This also may require that the slot-like opening 34 in the rocker 1 is replaced by a press-on roller corresponding to the friction roller.
  • Apparatus according to claim 1 further comprising means for preventing a flat item from being drawn into said apparatus by said drawing means when another flat item is in said apparatus.
  • Apparatus for the automatic insertion of cards comprising: a tiltable beam, means for cooperating with said beam to pull cards into said apparatus, means for cooperating with said beam to feed cards out of said apparatus, a first card sensing means adjacent said pull-in means responsive to the presence of a card to tilt said beam into cooperative pull-in relationship with said card pull-in means, and a second card sensing means responsive to the presence of a pulled-in card for tilting said beam into cooperative card feed-out relationship with said feed-out means.
  • Apparatus according to claim 4 wherein said cards are perforated with feed holes and have a uniform length, said feed-out means comprises a sprocketed feed roller, and said second sensing means further comprises means for initially causing a desired one of said feed holes in each said card to be brought into operative relationship with said feed roller.
